THE DRILL SERGEANT: Corazon Mining (ASX: CZN) declared the achievement of highly positive results from a recently completed Phase 2 metallurgical testwork program at the company’s Mount Gilmore cobalt-copper-gold project in New South Wales.
Corazon Mining completed the testwork on a composited sample of drill core from recent drilling undertaken at the Cobalt Ridge deposit.
The testwork follows Phase 1 metallurgical testwork results the company reported in March this year.
Corzon explained that the Phase 2 testwork targeted lower grade material than that tested in Phase 1, claiming it to have delivered exceptional results.
Using a simple flotation processing has yielded recoveries of 93.6 per cent cobalt and 98.4 per cent copper.
The concentrate mass represented only 5 per cent of the initial mass feed, with the concentrate grading at 2.02 per cent cobalt and 5.18 per cent copper.
The company tested mineralisation that included what it considers to be the ‘background’ grade for the main lode within the Cobalt Ridge deposit.
The assayed grade of the sample was 0.14 per cent cobalt, 0.32 per cent copper and 0.09ppm gold, providing a variation to the previously tested high-grade mineralisation in the first phase metallurgical testwork.
“On-going testwork for the Cobalt Ridge deposit will focus on defining the down-stream concentrate processing options and detailed process engineering studies,” Corazon Mining said in its ASX announcement.
“Results to date suggest excellent potential for the production of a concentrate for hydrometallurgical processing.”
